There are tons of cosmetologists who will come to your room for hair and makeup and a few who make you come to them. There are numerous threads on this board that you might find helpful, though they tend to recommend the same 2 or 3 companies. You just need to look at their portfolios and see if they do the style you want. I chose Patricia LeJeune because I wanted a more natural look, and I was so happy that I've hired her a few more times since the wedding.
As for steaming, DFTW lists two businesses that will come out to hotel to steam your gown, but when I called last year, only Carolyn Allen's would actually do it. They also have an amazing service where you can ship them your gown and they'll bring it to your room for you, then pick it up and ship it back to your home after the event so you don't have to schlep it. If you don't have them clean the gown, it's only $15 + shipping both ways.
